Why do different people like different music?	[ "So I was just wandering around Google, looking up the whole \"4 chord\" theory -- which suggests that there are 4 main chords that morph into the most popular and \"hit\" songs. I read this really cool article a few years ago discussing the science behind manufacturing \"hit music\" in the pop genre. I'm going to ...	[ "Neural adaption. Basically, your brain only cares about a change in stimuli rather than every stimulus that comes along. Your brain knows how to ignore a stimulus if it isn't changing. So, if you are tasting/feeling the same thing all the time, your brain is going to ignore it." ]
At which point in time did the mass manufacturing of weapons become the norm?	[ "For interchangeable parts I believe you would be looking at Colt firearms in the 1840's. Samuel Colt set up factories that were tooled to create the exact same weapon over and over again using the same parts. There might be an argument for the Brown Bess or a similar musket from the continent but I don't know enou...

Sorry for the Macabre Question: Why do bombings often result in 20-500 times as many injured fatalities	[ "Well, in general most things have an inverse squared function as distance changes So 2x the distance is 1/4 the sound or readability or damage due to blasts. 3x would be 1/9th etc. So if there was a grenade that let's say killed 90% of all things within 5 meters, it will only be killing let's say 10% of the things...	[ "All species have a typical \"litter size\" for when they successfully breed. It depends greatly on the amount of care the offspring require (this includes the energy put into the eggs). There is a trade-off between how many offspring you can make and the quality of those offspring [(Source)](_URL_4_) For example, ...
Why, if I awake from a bad nightmare, do I still feel the emotional, psychological and/or physical effects of this nightmare, even though I KNOW I was just dreaming?	[ "Your brain has told you that you are in trouble/scared/upset because that is what it was experiencing at the time. You are still alarmed, etc, upon waking up because your mind and body are still reacting to the signals it was being given. Once you are awake, the feelings start to wear off, but it may take a while ...	[ "Like many mammals, people have instincts to groom themselves to maintain health and attract mates. Part of our grooming instinct is to remove parasites, like ticks or lice. These bugs are not a common problem for many modern people (unless you live below the poverty line, or enjoy the outdoors in certain places). ...
Why is it that with pixels on a screen the colors red, green, and blue are used rather than the primary red, yellow, and blue?	[ "For light, the primary colors are red, green, and blue. The red, yellow, and blue you learn about in school are the primary colors for things you normally use in art, like paint. To be more accurate, red and blue are actually just the closest \"normal\" colors to the actual primary colors of paint. The real ones a...	[ "Basically, the human eye has something similar to the refresh rate of a computer monitor or the shutter speed of a camera. The eye's refresh rate is something like 10-15 Hertz, meaning that on timescales shorter than ~0.1 seconds, things blur together. So if you're driving past a fence, there might be several of t...
How or why are yawns 'contagious'?	[ "A hypothesis suggests that [contagious yawning](_URL_2_) is connected to the activity of [mirror neurons](_URL_0_), found in primates.

Do a Rhino's eyes ignore its horn the same way a person's eyes will ignore the nose because it's always there?	[ "A rhino's vision isn't very good to begin with; they rely mostly on their noses to know what's what. Their eyes are also located at the sides of their head in typical herbivore fashion, giving them a relatively wide field of view to the sides to spot movement (i.e., predators, rivals). Straight ahead is in their p...	[ "Hippopotamuses have adapted to utilize two unique acid secretions in their skin. The first is called \"hipposudoric acid\" and the second is called \"norhipposudoric acid\". Since these are strong acids, they deter the growth of bacteria on the skin. In addition, hipposudoric acid is colored bright red while norhi...
How dry aging meat doesn't make it dangerous.	[ "The outer meat is basically dried very quickly and, as already mentioned; bacteria thrive in a moist environment, therefore, bacteria colonies won’t or have a hard time growing on the meat. Also, when the outer, dried, shell is form it becomes very dense, protecting the interior from the outside. Also, muscles tha...

Do dark thunder clouds absorb the sun's heat, and does it affect the storm?	[ "As viewed from the sun, thunderstorms actually look white, just as any other high level cloud would look like. Here are some satellite images of [snow storms](_URL_1_) and [supercells](_URL_0_). The color of clouds you see from the surface is due to scattering and reflection of sunlight by the clouds.

How did the Soviet economy work?	[ "I've only read excerpts from the book, but [The Turning Point: Revitalizing The Soviet Economy](_URL_0_) is written by two Soviet economists. The book should give an insight into how the Soviet economy worked, as well as some of the problems it faced (such as full employment leading to overproduction of certain go...	[ "It depends. In the US and other 1st-world countries, you can use tax records, asset prices (assets are stocks, real estate, etc.), salary data and other freely-available data to come up with a good guess. Other countries might require some more guesswork, but the principle is the same." ]
What makes a joint crack/pop more than another? Eg, some people can crack their knuckles more than their back, some people can crack other joints to different degrees?	[ "Mainly a joint's ability to collect and hold gases, apparently the more you crack certain joints in your body the more prone they are to recollect and refill with greater pocket volume. I could never crack my knuckles back in the day, and when i did it would hurt like crazy. Now every time i make a fist it sounds ...	[ "It is due to the birth of recordings. Once recordings were available, people became more focused on being perfect (pitch, rhythm, etc).

How long does it take for our solar system to orbit the centre of the galaxy? How many times has it done so?	[ "I liked this question, I had to google it and find out myself. _URL_0_ \"According to NASA, even at this incredible speed, it still takes the solar system 230 million years to orbit the center of the Milky Way Galaxy one time.\"" ]	[ "Any physically straigth line will always appear arc shaped if it covers long enough area of your vision. Its just our brains can make us realise they are really straigth if there is enough context. For the case of milkiway center there isnt. Cameras can cause further confusion. Its like inverse version of the prob...
Why are upload speeds so much lower than download speeds?	[ "Because most people spend most of their internet bandwidth downloading, so internet providers optimize for that. Businesses often have it closer to 50/50, as they upload more than regular users." ]	[ "It also it partially due to your different genders. Males are designed to get rid of excess heat, more of their blood vessels are closer to the surface of their skin. Females, are designed to hold heat in. It traces back to how your body is wired for reproduction. With more blood vessels closer to the surface, he ...
If you leave metal in a liquid state does it eventually evaporate like water?	[ "with high enough temperatures it'll turn into a fog, and eventually iron rain. that happens on brown dwarf stars." ]	[ "Think of it as a fridge. An empty fridge will consume more power because there is nothing in it to \"control\" the requested temperature other than the seal on the door. Whereas a fridge full of food and liquids will consume less because they \"regulate\" the temperatures by quickly absorbing the changes that occu...
How did people cope before the creation of glasses?	[ "The Oxford History of Technology ( 1961) has the invention of spectacles with convex lenses quite early, in 1286- but this would work for long-sightedness, be essentially reading glasses. Concave lenses for short-sightedness were harder to make. But though they come finally at the later 15th century, it does not s...

Why do psychedelic plants exist evolutionarily?	[ "[here](_URL_4_) is an article about cats on LSD. we now know that both cats and humans are reacting to LSD, we can assume that many other animals will also do. as some of us know, being on psychedelics can be a pretty unpleasant experience, especially if you don't actually know that you are. in the long distant...	[ "OP should know that the same can be said about a lot of drugs, especially those used to treat psychiatric or neurological disorders.

What happens to illegal immigrants if they have no documentation and their identity home country cannot be found?	[ "My uncle tried to do that in the 60's by giving a new name, so he was allowed to stay in the country for 7 years. Then he got in trouble and they recognized where he was from because of the investigator they brought in who identified him by his accent. If you are from a country with a lot of immigrants though they...	[ "The Taxes tanken from our checks are estimates. Sometime people pay too much or too little. When doing our taxes we figure out how much we really owed. Some payed too much and get a refund. Some paid too little and need to make up the difference" ]
Why do some insect species have the male die during/after mating?	[ "Especially in insects, females often times need to feed to develop a full complement of eggs (synovigenic). Males will sometimes give a [nuptial gift](_URL_0_). Sometimes this gift (e.g. mantids) may be in the form of eating the entire male after mating. They are providing the female with nutrients, upping their c...	[ "Chariot crashes were quite common in Roman chariot races. Chariots jockeyed for a good position, trying to get their opponents to crash into the sides and dividing wall of the track.

Lots of Little Earthquakes...	[ "They can do, yes, but it depends how distributed they are. If they occur across the length of the fault, then yes - the stress is released gradually over time in these smaller events. If, however, they are only occurring along a small segment of the fault, then they can actually result in the build up of very big...	[ "Non-expert here, but isn't it just an adrenaline surge? It's just the muscles getting twitchy in preparation to bolt at any second. _URL_0_" ]
Are dogs having 'fun' when they play? Or is something else else happening?	[ "Humans have a huge capacity to anthropomorphise, so it's very easy for us to ascribe human feelings and characteristics to, well, anything, but especially an animal we love. Dogs probably don't have \"fun\" and feel emotions in the same way we do, but they do clearly exhibit playfulness, and enjoyment. Even if ...	[ "The general consensus is [attention and approval seeking](_URL_4_) or [medical issues](_URL_1_). In [domesticated animals](_URL_2_), the approval seeking is generally from the owner. Because we see this in wild animals as well, it can't just be a human-approval mechanism. The attention seeking can be extended to t...
Where do saltwater mammals such as whales, seals, etc, get drinking water?	[ "They primarily get water from food, both as water in the food and as a byproduct of metabolism (plants use water and CO2 to make food, and those come out again when the food is broken down). Some may drink some water, but most of the water comes from food. There are land animals that also get their water that way,...	[ "Usually there is a ramp next to where they are built, they support the ship with wood or some other materials, strategically placed, so when they take out some the ships slides through the ramp into the water.

Why did the public turn on Jimmy Carter so quickly?	[ "I know this doesn't directly answer your question, but I wrote a response a long time ago on [why Carter is considered a bad president](_URL_0_). There isn't a lot in my answer on public opinion, which is what it seems you're looking for, but it does discuss Carter's failures." ]	[ "\"Just about everyone here\" Where is \"here\" for you? It sounds like your question's premise is based on a small sample set based on personal observation. Before your question is addressed, you should be making sure the premise is valid..." ]
If light can escape a star that's burning why can't it escape after the star collapses into a Blackhole? Where's the extra mass come from?	[ "There's no extra mass, the collapse just concentrates the mass into a really fucking tiny space. The strength of a gravitational field is inversely proportional to the distance from the mass. That is to say that if you're half the distance away, you experience 4x the gravity. With a black hole being so small, it...	[ "Until fairly recently (that is to say, several billion years ago), the expansion of the universe was mostly the effect of inertia. In the very, very early universe, space was expanding very, very quickly and it slowed down over time. In fact, the expansion was slowing down because gravity was slowing it down. In ...
How quickly were toilets integrated into society once the idea came out?	[ "The idea is actually ancient, there were toilets in the ancient Harappan civilization and Minoan Crete. So I have a related question. Why did ancient plumbing technologies fall out of use?" ]	[ "It depends. Are you talking about the aristocracy? Amongst the samurai specifically? Or amongst the peasantry? Because, as you might guess, there are big differences between those groups." ]
Is the WWII movie representation of Russian and Japanese rush tactics accurate?	[ "Imperial Japanese forces did have men committing to seemingly (and sometimes were outright) suicidal attacks that had no tactical or strategic merit to them. But it's important to realize under what conditions these attacks were made. Suicidal charges were not made by well supplied, rested units that were in good...

Why is data consumption such an issue all of a sudden when years ago it was all unlimited?	[ "Streaming has gotten huge in the past few years, and companies are reluctant to upgrade their infrastructure (it's pricy!) so it could handle everyone streaming at once. They start adding data caps and throttling to decrease how much data their customers use. It sucks." ]	[ "A lot more people watch sporting events, maxing out the ESPN servers bandwidth (or whoever is streaming the video). I work for a cable company and we are flooded with calls on Sunday's during football season about ESPN or some other sports streaming being terrible." ]
Why do people claim that socialists have "never learned economic theory"?	[ "Its just an insult to throw. You can just as easily say this about capitalists and come up with a litany of reasons to support your argument. The economy is ludicrously complex and intersects heavily with politics. There are no pure democracies on earth, no pure capitalist states no purely socialist states and no ...	[ "A: All Scotsmen enjoy haggis. B: But my Brother is Scottish and he hates haggis! A: All true Scotsmen enjoy haggis. Simply put its changing definition of what you're discussing (scotsmen) to deliberately exclude any couter-examples." ]
What is the difference between an embassy and a consulate?	[ "An embassy is in a country's capital, while a consulate is in another city that isn't the capital. For example, Brazil's capital is Brasilia, so the US has an embassy in Brasilia, and a consulate in Rio de Janeiro." ]	[ "Ask Reddit is for personal opinions, stories, and the like.

if I saw a cop and ran away from him for no reason, does he have the legal right to arrest me?	[ "Cop here; In general, no. However based on [Illinois vs. Wardlow](_URL_0_) running may be considered reasonable suspicion (which is the legal standard for a detainment) depending on the circumstances- such as being in a high-drug area, the officer's knowledge of the suspect's past (we know a lot of the shitbag...	[ "If the acceleration of the car is zero, i.e. it is moving at a constant velocity, you might as well imagine it as being stationary.

Why do guys insist on sending unsolicited dick pictures. Does that ever REALLY work?	[ "Men are very visual creatures, and quick to arouse. A man can go from no arousal to immediately turned on just with a quick flash of a girl's boobs. As a result of this nature, many men don't grasp that women don't work the same way, and aren't interested much in seeing a dick unless already aroused. Combine that ...	[ "Novelty attracts, we are hard-wired to be curious." ]
Why does hot water come out white/cloudy from the tap but when I boil cold water it is transparent?	[ "The cloudy appearance is small bubbles of gas. Sometimes this is air that gets into the water system. It becomes dissolved in the water, and evolves into small bubbles of gas. Other times it is caused by chemical reactions within your piping, again creating gas within the pipes. This can be a sign of corrosion wit...	[ "High pressure steam is just regular old steam, at higher pressure (there are several arbitrary cut-off points for \"high-pressure\" depending on the application). Producing HP steam is just like producing LP steam (add heat and water), except you need to have specialized containers/piping that can handle the pres...
How do DJs, mash-up artists, and the like manage to get sample vocals from songs?	[ "A few ways 1. Get a vocals only track from the artist or music publisher. But that only happens if you go through official channels. 2. Get an instrumental version of the song, create an inversion of the track, use that to cancel out the instrumentals from the full song, so you're only left with vocals. Like show ...	[ "There can be many reasons: - hiding behind a VPN or TOR or another proxy, or all of those; remember that there still are countries where piracy is not regulated by law - initial seeding from a remote server - actually living in a country with no laws against piracy - all of the above I also doubt that they are *th...
how do chickens generate the shell of an egg	[ "I'm not a expert on chickens, but I'll explain it how I understand it. If I happen to be wrong, I hope someone else can correct me and clear it up for you. The reproductive system of a hen is very much a kind of conveyor belt or assembly line. By the time the egg gets to the uterus (shell gland) in a hen, the whol...

How do printers pick out one piece of paper if they are all stacked up?	[ "Rubber rollers with a lot of friction, spread across the sheet. This is really easy for thin sheets. (text weight paper) Sometimes on the bigger industrial printers they are air-fed. A blast of air separates the top sheet and guides it foreword to a rubber roller. I work with these printers." ]	[ "They don't. It's a marketing ~~lie~~ gimmick. I used to work for a company that did a similar thing by mail. New customers were supposed to sign up by a certain time for special rates but as a specific matter of policy we'd give those rates to anyone who mailed back the special offer." ]
Why do new pillows smell so bad?	[ "Maybe cause it takes in all the sweat, grease, and drool while you're sleeping.

Is there any evidence genetic factors that predispose an individual person to having offspring of only one sex?	[ "If a woman has a recessive but lethal genetic flaw on one of her X chromosomes, this will skew her surviving offspring towards females. If we say that the woman has one healthy X chromosome (X) and one flawed one (Xb), and the father of her children has a regular X and Y, there are four possible combin...	[ "Sure. Look at (domestic) cats and dogs. They differ physically far more than humans do.

Here in the Toronto area they are alm...
How does light from very far away reach earth unobstructed?	[ "Space is mostly empty, so any photon that we can detect has not been absorbed by something else. We obviously can't detect light that has been obstructed by an object, but we can detect the absence of light in a particular patch of sky. For example, the nebula [Barnard 68](_URL_0_) shows up as a dark patch in th...	[ "Various reasons, but generally it's atmospheric distortion due to temperature gradients. Think about opening your door in the winter and watching the air shimmer as the heat goes out, or looking over a hot car in the summer. Same effect, larger distances.:)" ]
Why is it more expensive for me to fly non-stop a short distance, than it is for me to make a connection four states away and come back?	[ "More people want the direct flight. Higher demand leads to higher prices." ]	[ "Because of Newton's First Law of Motion: \"In an inertial reference frame, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force.\" You were moving along with the surface when you jumped or whatever and being in the air doesn't change that." ]
The core concept and basic techniques of Social Engineering	[ "What kind of social engineering are you referring to?

Would it have been completely impossible to decode hieroglyphics without the rosetta stone, or could we do it with modern linguistics/cryptography?	[ "It'd be doable, but challenging. Another unknown script, Linear B, was successfully figured out by the 1950s. We have far more inscriptions to work with in Egyptian than in Linear B, giving us a large sample size. Additionally, knowing Demotic (a liturgical language descended from Ancient Egyptian) and other Semit...	[ "Sort of. As you can see in Jurassic park 3, they can find out the shape of the voice box and get an idea of the nature of their vocals.

If Earth and every planet is falling towards our Sun, and our solar system is falling towards our galactic center, where is our entire galaxy falling towards, and if it isn’t falling, what force is holding it up?	[ "The OP is correct in using falling as relative between the two objects. The earth “falls” towards the sun, just is going too fast and so always misses. The Milky Way, as far as I understand, is falling towards andromeda galaxy, eventually to “collide” and become a big super galaxy. Any one galaxy is always attract...	[ "Falling with Style.

We don't \"think a...
Is there a terminal velocity to 'natural' objects in space?	[ "Sort of, but only in the sense that nothing can go faster than the speed of light. This isn't really \"terminal velocity\" with the real definition given by the other posters." ]	[ "only if it's structure is perfectly non-[amorphous](_URL_0_) so that it wouldn't start contorting with the inertial effect commonly known as the [centrifugal force](_URL_1_).

Regarding our early marine-based ancestors, what was the evolutionary advantage to leaving the water and becoming land animals?	[ "The land at that time was filled with resources and shelter that was not being utilized by any other animals. Being able to make use of those resources is a significant survival advantage over competing organisms that could not use them. The small genetic variation you are thinking of is less like a fish sprouting...	[ "Specializing helps with optimization. Cows can't eat meat, but their teeth and multiple stomachs are ideal for eating grass. Humans have to have sharp teeth for meat and grinding teeth for plants and our digestive system is inefficient at processing plant matter. Versatility is obviously useful, but there are trad...
What is the hottest a microwave can heat something up?	[ "The true limit on a microwave oven will be how fast heat gets conducted out and how well you can couple the energy into your target. Microwave generating machines can be used to heat fusion plasmas _URL_0_ so long as they are given enough power." ]	[ "In order for the egg to fry, it needs to hit 158 deg F.

Can a recessive gene emerge from two dominate gene parents?	[ "From a Mendelian perspective, yes, if they are both heterozygous, meaning they have one copy of the dominant allele and one of the recessive allele, then there is a 1/4 chance of a recessive offspring. The reverse, however, is not true. Two individuals who show a recessive phenotype will never produce offspring wh...	[ "The opposite of that is more likely to be true. What you're asking is roughly analogous to suggesting that melting all the crayons together would give you more colors." ]
Do laxatives, (e.g. Coffee), help your body expel excess calories quicker?	[ "It will decrease transit time and thus decrease nutrient absorption. So, yeah, it'll work, but it might not be the best idea because you won't just excrete extra calories. You'll also lose some absorption of good stuff like vitamins and all. Edit: Coffee probably is not be a strong enough laxative to cause weight ...

Why are 'do' and 'don't' pronounced differently? If 'do' is pronounced 'doo', shouldn't 'don't' (do not) be pronounced 'doont'?	[ "It's just one of those quirks of the English language. \"Won't\", for \"will not\", adds an 'o' before the 'n', which makes even less sense. Languages change over time, and clunky pronunciations like \"doon't\" or \"willn't\" get smoothed down to easy pronunciations." ]	[ "Imagine you have 3 bags of treats. One is Oreos (Apple OSX), the other is Skittles (Windows), and finally Nutella (Linux). All of these treats are absolutely delicious. With Oreos, it is what you get.

Water level of ice water before and after melting.	[ "The level will stay the same. Reason: The ice, when floating in the water, is displacing its weight, pushing exactly that much water away from itself. After melting, the same weight of water is present, thus displacing the same amount of water." ]	[ "The vodka, since a change of state takes extra energy and the difference in specific heat of alcohol and water isn't enough (or even a difference in the right direction in this case) to counteract this." ]
